SASH-FASTENER SPECIFICATION forming part of Letters Patent No. 283,896, dated 'August 28,1883.

Application filed December 2S, 1882. (No inode.)

T a/ZZ whom it may. concern:

Be it known that I, ELEAZER KnirrsirALL, of New Britain, in the county of Hartford and State of Connecticut, have invented certain 5 new anduseful Improvements in Sash-Fasten ers, of which the following is a specification.

My'invention relates to that class of sashfasteners which have a spring-pressed longitudinally-moving bolt; and the objects of my Io invention are to simplify the construction, thereby reducing the cost, to avoid riveting, and to enable the bolts, when desired, to be made of common cast-iron. I attain these objects by the simple construction illustrated in the accompanying drawings, in which- Figure I is a side elevation of one of my sashfasteners. Fig. 2 is a longitudinal section thereof on line m w of Fig. I, showing the bolt and spring in elevation. Fig. 3 is a side elevation of the ring for securing the bolt within the case, and Fig. 4 is aside elevation of another sash-fastener which embodies my invention.

A designates the case, which may be made of any desiredform, either with or without a i screw-thread on its periphery.

B designates the spring-pressed longitudinally-moving bolt, 'fitted within the case by a bearing at each end in the ordinary manner, 3o and provided with a shoulder, a, for the end of the spring b to press against, while the other end oi' said spring bears against the case. I make the bolt B of such form that it may be slipped into the case, and so that a portion of it projects through the small end of the case, as shown. I form an annular groove, c, in the bolt at a point which, when the bolt is in its normal position, is just outside of the small I also form a ring, (l, whose end of the case.

ends do not quite meet each other, as shown 4o in Fig. 3, and of such a size that it may readily be slipped over the small end of the bolt.

In order to assemble the parts it is only necessary to put the spring on the bolt, pass the bolt through the oase until the groove 0 is outside ofthe small end of the case, then slip on the ring and compress it into the groove. This latter operation will preferably be done in a press or other machine having dies of suitable shape to engage the ring and set it in place. The ring should be or soit metal, so as not to spring back out of place when set in the groove. The ring then holds the parts in their assembled position and makes a neat and cheap 4 Figs.` I and 2 show that style of a sash-fastener which has'the projecting handle on the small end of the bolt, and Fig. 4 shows that style which has the handle or` thumb-pad e upon the same end of the bolt with the locking shoulder.

A designates the case, B the bolt, and c the groove in which the ring cl is set.

Sash-fasteners of the same general form as those herein shown, but without the groove and ring, are old, and are hereby disclaimed.

I claim as my invention# The herein-described sash-i'astenen consisting of the case, the spring-pressed longitudinally-moving-bolt having the annular groove, and the ring set in said groove to hold the parts in their assembled position, substantially as specied.
